Specification of Letters Patent.

Patented May 21, 1912.

Application filed J'anuai 25, 1910, Serial No. 539,984. Renewed September 16, 1911. Serial No. 649,736.

To all whom it may concern:

Be it known that I, EMIL A. Lanna, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented new and useful Improvements in Lamps, of which the following is a specification.

This invention relates to oil burning lamps provided with means for generating oxygen and supplying the same to the burner for producing a better combustion and greater illuminating power without vitiating the air in the room Where the lamp burns.

The invention has for one of its objects to improve and simplify the construction and operation of devices of this character so as to be comparatively simple and inexpensive to manufacture, reliable and eflicient in use, and readily and conveniently manipulated.

Another object of the invention is the provision of a novel arrangement of oxygen generating means so combined with the lamp burner as to deliver a controllable supply of oxygen to the burner. A further object of the invention is to provide an improved arrangement and organization of the parts whereby the generator and lamp reservoir can be conveniently recharged from time to time.

With these objects in view and others, as will appear as the description proceeds, the invention comprises the various novel features of construction and arrangement of parts which will be more fully described hereinafter.

In the accompanying drawings which illustrate one embodiment of the invention, Figure 1 is a central vertical section of the lamp. Fig. 2 is a horizontal section on the line 2-2 of Fig. 1. Fig. 3 is a horizontal section on the line 3-3 of Fig. 1. Fig. 4 is a horizontal section on line 4-4 of Fig. 1, showing the slide valve of the burner, and Fig. 5 is a detail of the air valve of the generator.

Similar reference characters areemployed to designate corresponding parts throughout the views.

In the present instance, I have elected to illustrate the invention as embodied in lantern form, but it is to be understood that it may be used for a table or any other kind of lamp.

Referring to the drawings A designates a water reservoir having near its upper edge the screw thread 1 to receive the threaded cap 2. The reservoir A has its bottom provided with an outwardly inclined flange 3 which is perforated vertically at diametrically opposite points 4 to receive the threaded lower ends of the side bars 5 of the lantern frame. Suitable nuts 6 are applied to the ends of the bars 5 whereby the reservoir is suspended therefrom. The reservoir A is also provided with a centrally arranged cylindrical compartment 7 the wall 8 of which has its lower edge formed with the arch shaped openings 9 through which water'fiows from the reservoir A. Immediately above the openings 9 and integral with the inner face of the wall 8 is an annular shelf 10 adapted to support the chemical container 11. The cap 2 has an upwardly projecting and interiorly threaded flange 12 into which is adapted to be screwed the hollow plug 13. The opening inthe plug 13 is constricted at its upper end to provide the air inlet 14 which is closed by the pivoted slide 15. When the opening 14 is uncovered, air will pass into the reservoir A and exert a pressure on the contained water forcing the same through the opening 9 int-o the compartment 7 and onto the oxygen producing chemical in the chemical container or package 11. The chemical package is formed of a porous material, as for instance a porous stone or a fabric. The chemical which is preferably used to produce the oxygen by contact with the water is calcium and sodium peroxid in fusedform.

Suitably disposed above the reservoir A is a second reservoir B adapted to contain oil, or other hydrocarbon illuminating fluid. Secured to the bottom 16 of the oil reservoir B by any suitable means is a downwardly tapered wall 17 forming a compartment 18 for oxygen. The smaller end of the wall 17 is provided with an interiorly threaded nipple 19 into which is screwed the short pipe 20 whose lower end is threaded into an aperture 21 in the center of the cap 2. The pipe 20 has seated therein a turning plug valve 22, by means of which the flow of oxygen is controlled from the compartment 7 to the compartment 18.

Circular passages 28 are formed in the reservoir B, through which the oxygen conduits 24 pass to the bottom of the panshaped member 25 which supports the gal- 25, and has the handle 25.

lery 26 of the burner 27. Suitable draft openings 26 are formed in the gallery 26. The bottom of the pan-shaped member 25 is provided with a plurality of air inlet openings 25 which are controlled by the perforated slide 25". The slide 25 is formed with the parallel arms 25 supported on the under side of the member 25 by the brackets By means of the slide 25 air may be admitted to the burner when it is not necessary to use oxygen.

The oil reservoir B is slidably mounted on the bars 5 of the frame of the lantern by means of the oppositely disposed brackets 28.

The wick tube 31 is threaded into an in teriorly threaded enlargement 32 in the center of the upper wall of the oil reservoir B and the burner cap is slidably seated on the wick tube.

A sliding frame C is mounted between the side bars 5, and comprises the rings 34 and 85, to which is secured the guard 36 for the chimney 37. The upper of the rings 34 supports the canopy or hood 88 and draft guard 39, which draft guard is provided with the outlet openings 40 and 40 and the annular ledge 41, which retains the upper end of the chimney 37. The openings 40 discharge into the annular chamber space 46 in the canopy 38 and thence passing through the ports 40 in the bottom of said chambers to the atmosphere, the construction being such that back drafts are prevented and a steady burning will be secured. The upper ring 34 is also provided with the brackets 42 which embrace the bars 5. The lower ring 35 has the forked arms 43 which engage with the guiding strips 44 on the inner faces of the bars 5.

To the upper ends of the bars 5 is secured, by the rivets 44, the handle or bail 45, by means of which the lantern may be conveniently carried.

The sliding frame 0 is provided with a spring catch 48 secured to one of the arms 48, on the lower ring 35, and adapted to engage its lug 48 in one of the notches 49 and 50 in one of the side bars 5 for holding the frame in either raised or lowered position. By pressing the latch inwardly, the frame C can be moved upwardly past the notch 49 to uncover the burner and wick. The brackets 42 will slide upward on the handle 45 and the latch engage the notch 50.

With a lamp of this construction the supply of oxygen for combustion can be wholly independent of the atmosphere or in cOnjunction therewith. This artificial supply of oxygen insures brilliant burning and especially is this so, when the lamp or lantern is used in smoky or gaseous atmospheres. Furthermore, a lamp of this peculiar form is especially valuable for use on fast moving. vehicles, as it needs no sup' ply of outside air, and with its own steady supply of oxygen and means for preventing back draft a steady flame can be secured.

lVhen used in the ordinary atmosphere, the valves 15 and 22, are closed, the valve 15 preventing influx of air to the chamber A and the valve 22 preventing the flow of oxygen to the burner. The slide 25* is manipulated to register the openings 25 in the member 25 and those in the slide 25, which admits atmosphere to the burner cap, through the openings 33 and to the point of combustion of the wick, through the opening 26 in the gallery 26.

hen it is desired to recharge the reservoir B the nuts 6 are removed and the chamher A unscrewed from the cap 2 or the reservoir B together with A may he slipped off the side bars 5, and the cap 2 then removed.

From the foregoing it will be evident that I have provided a lantern which is simple and effective in operation and which includes eflicient means to produce a steady and brilliant flame under various adverse conditions.

Having thus described the invention, what I claim is 1. A lamp or lantern having a hydrocarbon chamber, an oxygen generating chamber, a water supply chamber communicating with said oxygen chamber, and oxygen ducts passing through the hydro-carbon chamber.

2. A lamp or lantern having. a hydro-carbon chamber, containing a wick, an oxygen generating chamber, a water chamber communicating therewith, ducts for discharging oxygen adjacent the wick, and controlling means in the oxygen. j

3. A lamp or lantern comprising a frame, an oil chamber, a water chamber, and an oxygen generating chamber secured within the frame.

4. A lamp or lantern comprising a frame, and an oil chamber, a water chamber and an oxygen generating chamber removably secured within the frame.

5. A lamp or lantern comprising. a frame, a burner, an oxygen generator, and means for conveying oxygen to the burner.

6. A lamp or lantern comprising. a frame. an oil burner secured within the frame, a chamber surrounding the oil burner, an oxygen generator, and means for discharging oxygen within the chamber of the burner.

7 A lamp or lantern comprising a frame having an oil chamber, a burner and wick, removably secured thereto, an oxygen generating chamber, a water chamber communicatin-g with the oxygen chamber, and an oxygen duct leading'fromthe oxygenchamber and passing through the oil chamber.

8. A lamp or lantern comprising a frame, a globe carrier slidab'ly mounted on the frame, an oil burning means including an oil chamber, 'a burner and Wick, a compartment on the oil chamber, oxygen generating meansv removably secured to the frame, means for conveying oxygen Within the compartment, and air controlling means on the oil burner.
